2.2.17 MULTIPLE RECORD TRANSMISSION. The
2780
Emulator allows the specification of
the number of records to be placed in a block for transmission or reception. When communicating
with an IBM 2780 with the multiple record transmission feature installed or with an IBM host, up to
seven records (or not more than 400 characters) may be transmitted or received. The
3780
Emulator
allows as many records as will fit in a block to
be
transmitted or received. When communicating with
an
IBM 3780
or with an
IBM
host, as many records as will fit in a block
(512
characters) may be
transmitted or received.
